A: When a baby is​ born, it is a girl.

​B: When a 7​-sided die is​ rolled, the outcome is 4.

 

Find​ P(A and​ B), the probability that events A and B both occur.

 

A: a baby can be girl or boy the probability getting one of them is \(\frac12\)

 

B: on the 7 sided die 7 numbers so the probability getting 4 is \(\frac17\)

 

Answer:\(\frac12\times\frac17=\frac1{14}\)
